Abstract

PURPOSE: The efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of pediatric urolithiasis was evaluated, and a retrospective analysis of the feasibility of various methods of pain control for ESWL performed according to the age of the patients.
MATERIALS AND METHODS
Between 1987 and 2004, 30 boys and 32 girls diagnosed with urolithiasis were treated. Their records were reviewed and analyzed for metabolic and anatomical anomalies, the size and location of the stones and for the treatment outcomes and complications.
RESULTS
The success rates were 27.4, 61.3 and 80.6% after one, two and three sessions of ESWL, respectively, with an overall success rate of 93.5%. The locations of the stone were the upper calyx, the mid calyx, the lower calyx, the upper ureter, the mid ureter and the lower ureter in 6, 4, 7, 15, 4 and 25 cases, respectively. All patients underwent ESWL with a piezoelectric lithotriptor (EDAP LT02). There was only one patient who required general anesthesia. Most of the patients younger than 6 years underwent the ESWL with IM or IV sedation only. Generally, the patients older than 6 years old required no sedation. Pyelonephritis occurred in one patient (1.6%).
CONCLUSIONS
ESWL is an efficient and safe treatment modality for pediatric urolithiasis. Patients older than 6 years can undergo ESWL with analgesics or oral sedation only.
